## Objectives

Students will leave the course able to use Excel to build statistical models that answer questions such as:

• What's the relationship between a variable and an outcome?
• If I adjust X, what will be the impact on Y?  Are there natural limits I should be aware of?
• What's coming next?  Are we going up or down and by how much?
• Why are we going up or down?  How impactful is each variable?  (In other words, what should I focus on first?)
• Are there any unusual outliers?  What caused those?  Do I need to do something about this?
• How likely is any given idea or decision or campaign to be successful? (i.e., logistic regression)
• Did any given change or decision make a material business impact?

## Prerequisites

Students have access to Microsoft Excel and are familiar with writing calculations and formulas within Excel.
